驻村第一书记制度是中国共产党农村工作在新世纪的重要制度创新,也是中国特色社会主义制度的重要组成部分,在推进精准扶贫、全面建成小康社会过程中发挥了显著的作用。不过,需引起重视的是,在继脱贫攻坚之后的乡村振兴战略中,驻村第一书记制度存在的隐性不足,可能会被放大,从而抑制制度目标的实现。在全面推进乡村振兴的过程中,需要用好驻村第一书记制度,更需要从制度上进行调整,引导驻村第一书记走实走深群众路线,助推农村基层组织有序运转,推进强村富民,提升乡村治理水平。通过角色重构与职能优化,将驻村第一书记的工作重心从为村庄争取外部资源转移到引领乡村组织振兴、激活村庄可持续发展的内生动力上来,最大限度发挥驻村第一书记制度优势。

Oxidative coupling of cinnamic acid derivatives and their radical-scavenging activities

Chinese Science Bulletin 2010年第25期55卷 2885-2890页

作者： JIN XiaoLing YANG RuTing SHANG YaJing DAI Fang QIAN YiPing CHENG LiXia zhou Bo LIU zhongli State Key Laboratory of Applied Organic Chemistry Lanzhou University Lanzhou 730000 China

4-Hydroxycinnamic acid derivatives,including ferulic acid (FA) (1),sinapic acid (SA) (2) and caffeic acid (CA) (3),are widely distributed in the plant kingdom,and undergo oxidative cross-coupling leading to the corresponding dehydrodimers,trimers and even higher oligomers in plants. In order to evaluate the antioxidative ability of these 4-hydroxycinnamic acid derivatives and their oligomers,we synthesized 8-8'-bis-lactone-dimers (8-8'-DiFA (4),8-8'-DiSA (5) and 8-8'-DiCA (6)),as well as a new trimer (7),by the reaction of the corresponding monomers (1-3) with Ag2O in methanol,and assayed their free radical-scavenging activity by the reaction with 2,2-diphenyl-1-picrylhydrazyl radical (DPPH·). It was found that CA (3) and 8-8'-DiCA (6) bearing o-dihydroxyl groups exhibited significantly higher radical-scavenging activity than those bearing no such groups,and oxidative coupling of CA (3) resulted in remarkable enhancement in the activity.

Time-dependent water permeation behavior of concrete under constant hydraulic pressure

引用

Water Science and Engineering 2008年第4期1卷 61-66页

作者： Fang Yonghao Wang zhongli zhou Yue College of Materials Science and Engineering Hohai University Nanjing 210098 P. R. China

In the present work, a concrete permeability testing setup was designed to study the behavior of hydraulic concrete subjected to constant hydraulic pressure. The results show that when concrete is subjected to high enough constant hydraulic pressure, it will be permeated, and after it reaches its maximum permeation rate, the permeability coefficient will gradually decrease towards a stable value. A time-dependent model of permeability coefficient for concrete subjected to hydraulic pressure is proposed. It is indicated that the decrease of the permeability coefficient with permeation time conforms well to the negative-exponential decrease model.

乡村组织振兴是乡村组织体系的系统构建,包括建立和完善以党的基层组织为核心、以村民自治和村务监督组织为基础、以集体经济组织和农民合作组织为纽带、以各种经济社会服务组织为补充的组织体系。驻村第一书记兼具组织资源和乡村治理资源双重优势,为乡村组织振兴提供了干部人才支撑,在建强村党组织、推进强村富民、提升治理水平和为民办事服务等方面发挥了重要作用。然而,因特定的运行与考核方式,驻村第一书记制度对下负责机制还不够健全,一定程度弱化了村级党组织的组织功能,具体表现为驻村第一书记对村级党组织组织力建设重视不够、培育各类农村经济组织的动力不足、与村庄内部各治理主体互动不足、对乡村社会组织的培育和帮扶成效不明显。在助推乡村组织振兴过程中,驻村第一书记要以全面推进乡村振兴为目标,把增强政治功能和组织功能作为建强村党组织的着力点,因地制宜,创新拓展基层党组织对农村工作全面领导的实现路径,探索引领村级党组织组织力提升,推动“一肩挑”背景下村级党组织更加高效健康运行,并推进党组织引领各类村级组织积极发挥作用,确保乡村社会充满活力、安定有序。
